CROSS-REFERENCE TO RELATED APPLICATION(S)

This application claims priority under 35 U.S.C. 119 and 365 to Korean Patent Application No. 10-2019-0056604, filed in Korea on May 14, 2019 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.

BACKGROUND 1. Field

A fermentation and aging apparatus is disclosed herein.

2. Background

Beverages are collectively referred to as drinkable liquids, such as alcohol or tea. For example, beverages may be divided into various categories, such as water (a beverage) for quenching thirst, juice beverages with a unique flavor and taste, refreshing beverages giving a refreshing sensation, favorite beverages with a stimulant effect, or alcoholic beverages with an alcohol effect.

A representative example of such a beverage is beer. Beer is an alcoholic beverage produced by making juice of malt, which is made by sprouting barley, filtering the juice, adding hop, and fermenting yeast.

Consumers may purchase ready-made products made and sold by a beer maker or may make beer at home (hereinafter “homemade” beer) produced by directly fermenting beer ingredients at home or in a bar. Homemade beer may be made in a variety of types rather than ready-made products and may be made to better suit a consumer's taste. The ingredients for making beer may include water, liquid malt, hop, yeast, and a flavoring additive, for example.

Leaven, which is called yeast, may be added to liquid malt to ferment the liquid malt and assist production of alcohol and carbonic acid. Flavor additives are additives that enhance the taste of beer, such as fruit, syrup, and vanilla beans, for example.

Generally, homemade beer may include three stages or operations, namely, a wort stage or operation, a fermentation stage or operation, and an aging stage of operation, and it may take about two to three weeks from the wort stage or operation to the aging stage or operation. Maintaining an optimum temperature during the fermentation operation is important for homemade beer, and the easier the beer is to make, the more user convenience is improved.

Recently, a fermentation and aging apparatus capable of easily making a beer-like beverage at home or in a bar has been gradually used. Such a fermentation and aging apparatus is configured to be convenient.

When beverage is made using the fermentation and aging apparatus, ingredients used to make the beverage may include a fluid, such as water, an object to be fermented and an additive, for example, a fermentation accelerator. When beer is made using the fermentation and aging apparatus, ingredients for making the beer may include water, malt, yeast, hop, and flavoring additives, for example. The fermentation and aging apparatus may include all of the ingredient supplier 3 and the fermentation container 12. The ingredients for making the beverage may be accommodated separately in the ingredient supplier 3 and the fermentation container 12. That is, a portion of the ingredients, for example, ingredients to be fermented, for making the beverage may be accommodated in the fermentation container 12, and the remaining ingredients may be accommodated in the ingredient supplier 3. The remaining ingredients accommodated in the ingredient supplier 3 may be supplied to the fermentation container 12 together with the fluid supplied from the fluid supply module 5 and mixed with the portion of the ingredients accommodated in the fermentation container 12.

A main ingredient (ingredients to be fermented) that is essential for making a beverage may be accommodated in the fermentation container 12, and the other ingredients or additives, for example, a fermentation accelerator, added to the main ingredient may be accommodated in the ingredient supplier 3. In this case, the additives accommodated in the ingredient supplier 3 may be mixed with fluid supplied from the fluid supply module 5 and supplied to the fermentation container 12 and then mixed with the main ingredient accommodated in the fermentation container 12.

An amount of the main ingredient accommodated in the fermentation container 12 may be greater than an amount of other ingredients. For example, when beer is made, the main material may be malt of malt, yeast, hop, and flavoring additives. Also, the additive accommodated in the ingredient supplier 3 may be the other ingredients except for the malt of the ingredients for making beer, for example, yeast, hop, and flavoring additives.

According to one embodiment, the fermentation and aging apparatus may not include the ingredient supplier 3 but may include the fermentation container 12. In this case, the main ingredient may be accommodated in the fermentation container 12, and the user may directly put the additives into the fermentation container 12.

If the fermentation and aging apparatus includes both the ingredient supplier 3 and the fermentation container 12, the beverage may be more easily made. Hereinafter, a case in which the fermentation and aging apparatus includes both the ingredient supplier 3 and the fermentation container 12 will be described as an example. However, embodiments are not limited to the case in which the fermentation and aging apparatus includes both the ingredient supplier 3 and the fermentation container 12.

The ingredients within the fermentation container 12 may be fermented over time, and the beverage made in the fermentation container 12 may flow to the second main channel 42 through the main channel connecting portion 115 and also flow from the second main channel 42 to the beverage dispenser 6 to be dispensed. The ingredients that are necessary for making the beverage may be accommodated in the ingredient supplier 3, and the fluid supplied from the fluid supply module 5 may pass through the ingredient supplier 3. For example, when the beverage made in the fermentation and aging apparatus is beer, the ingredients accommodated in the ingredient supplier 3 may be yeast, hop, and flavoring additives, for example.

The ingredients accommodated in the ingredient supplier 3 may be directly accommodated into the ingredient receivers 31, 32, and 33 provided in the ingredient supplier 3. At least one ingredient receiver 31, 32, and 33 may be provided in the ingredient supplier 3. Also, a plurality of ingredient receivers 31, 32, and 33 may be provided in the ingredient supplier 3. The plurality of ingredient receivers 31, 32, and 33 may be partitioned with respect to each other.

Inlets 31 a, 32 a, and 33 a, through which the fluid may be introduced, and outlets 31 b, 32 b, and 33 b, through which the fluid may be discharged, may be provided in the ingredient receivers 31, 32, and 33, respectively. The fluid introduced into the inlet of one ingredient receiver may be mixed with the ingredients within the ingredient receivers and then discharged through the outlet.

The ingredients accommodated in the ingredient supplier 3 may be accommodated in ingredient containers C1, C2, and C3. The ingredient containers C1, C2, and C3 may be accommodated in the ingredient receivers 31, 32, and 33, and each of the ingredient receivers 31, 32, and 33 may be referred to as an “ingredient container mount.” The ingredient containers C1, C2, and C3 may be a capsule, or a pod, for example; however, embodiments are not limited thereto.

When the ingredients are accommodated in the ingredient containers C1, C2, and C3, the ingredient supplier 3 may be configured so that the ingredient containers C1, C2, and C3 may be seated therein and withdrawn therefrom. The ingredient supplier 3 may be provided as an ingredient container kit assembly in which the ingredient containers C1, C2, and C3 are separably accommodated.

For example, a first additive, a second additive, and a third additive may be accommodated in the ingredient supplier 3. The first additive may be a fermentation accelerator, for example, yeast, the second additive may be hop, and the third additive may be a flavoring additive. The ingredient supplier 3 may include a first ingredient container mount 31 in which a first ingredient container C1 containing the first additive may be accommodated, a second ingredient container mount 32 in which a second ingredient container C2 containing the second additive may be accommodated, and a third ingredient container mount 33 in which a third ingredient container C3 containing the third additive may be accommodated.

The ingredients contained in the ingredient receivers or the ingredient containers C1, C2, and C3 may be extracted by a fluid pressure of fluid supplied from the fluid supply module 5. When the ingredients are extracted by the fluid pressure, the fluid supplied from the fluid supply module 5 to the first main channel 41 may pass through the ingredient receivers or the ingredient containers C1, C2, and C3 and then may be mixed with the ingredients, and the ingredients accommodated in the ingredient receivers or the ingredient containers C1, C2, and C3 may flow to the second main channel together with the fluid.

A plurality of different additives may be accommodated separately in the ingredient supplier 3. For example, when beer is made, the plurality of additives accommodated in the ingredient supplier 3 may be yeast, hop, and a flavoring additive, which may be accommodated separated from each other.

When the plurality of ingredient receivers is provided in the ingredient supplier 3, the plurality of ingredient receivers 31, 32, and 33 may be connected in series to each other in a flow direction of the fluid. That is, the ingredient supplier 3 may include at least one connecting channel 311 and 312 that connects the outlet of one ingredient receiver of the plurality of ingredient receivers 31, 32, and 33 to the inlet of another ingredient receiver.

Also, the plurality of ingredient receivers 31, 32, and 33 may include an initial ingredient receiver 31 and a final ingredient receiver 33. The plurality of ingredient receivers 31, 32, and 33 may further include an intermediate ingredient receiver 32.

The inlet 31 a of the initial ingredient receiver 31 may be connected to the first main channel 41, and the outlet 33 b of the final ingredient receiver 33 may be connected to the second main channel 42. The intermediate ingredient receiver 32 may be disposed between the first ingredient receiver 31 and the second ingredient receiver 33 in the flow direction of the fluid. The inlet 32 a and the outlet 32 b of the intermediate ingredient receiver 32 may be connected to different connecting channels 311 and 312 from each other.

As illustrated in FIG. 1 , when three ingredient receivers are provided in the ingredient supplier 3, the outlet 31 b of the initial ingredient receiver 31 may be connected to the inlet 32 a of the intermediate ingredient receiver 32 through the first connecting channel 311, and the outlet 32 b of the intermediate ingredient receiver 32 may be connected to the inlet 33 a of the final ingredient receiver 33 through the second connecting channel 312. The fluid introduced into the inlet 31 a of the final ingredient receiver 31 through the first main channel 41 may flow to the first connecting channel 311 through the outlet 31 b together with the first additive accommodated in the initial ingredient receiver 31.

The fluid, which may be a mixture of water and a first additive, introduced into the inlet 32 a of the intermediate ingredient receiver 32 through the first main channel 311 may flow to the second connecting channel 312 through the outlet 3 b together with the second additive accommodated in the intermediate ingredient receiver 32. The fluid, which may now be a mixture of water and first and second additives, introduced into the inlet 33 a of the final ingredient receiver 33 through the second main channel 312 may flow to the second connecting channel 42 through the outlet 33 b together with a third additive accommodated in the final ingredient receiver 33. The fluid, which may now be a mixture of water and first, second, and third additives, discharged through the second main channel 42 may be guided to the main channel connecting portion 115 of the fermentation module 1 and then introduced into the fermentation container 12.

However, the configuration of the ingredient supplier is not limited thereto. For example, when the intermediate ingredient receiver is not provided, two ingredient receivers may be provided in the ingredient supplier 3. In this case, one ingredient receiver may be the initial ingredient receiver, and the other ingredient receiver may be the final ingredient receiver. The outlet of the initial ingredient receiver and the inlet of the final ingredient receiver may be connected to each other by the connecting channel.

For another example, when a plurality of the intermediate ingredient receiver is provided, four or more ingredient receivers may be provided in the ingredient supplier 3. In this case, one ingredient receiver may be the initial ingredient receiver, another ingredient receiver may be the final ingredient receiver, and the remaining ingredient receivers may be intermediate ingredient receivers. In this case, as the connection between the ingredient receivers in series is easily understood by a person skilled in the art, detailed descriptions thereof have been omitted.

As the plurality of ingredient receivers 31, 32, and 33 may be connected in series to each other, the channel configuration of the ingredient supplier 3 may be simplified. Further, as the additives contained in the ingredient containers C1, C2, and C3 may be extracted all at once, a time taken to extract the additives may decrease. Furthermore, as the user does not have to worry about a mounting order of the ingredient containers C1, C2, and C3, malfunction due to the mounting of the ingredient containers C1, C2, and C3 in an erroneous order may not occur. Also, fluid leakage in the ingredient supplier 3 may be minimized to improve reliability.

When the ingredients accommodated in the ingredient supplier 3 are accommodated in the ingredient containers C1, C2, and C3, the initial ingredient receiver 31 may be referred to as an “initial ingredient container mount”, the intermediate ingredient receiver 32 may be referred to as an “intermediate ingredient container mount”, and the final ingredient receiver 33 may be referred to as a “final ingredient container mount”.

That is, the fermentation and aging apparatus utilizes the fermentation container 12 and the ingredient containers C1, C2 and C3, thereby accurately providing the amount of ingredients necessary to make the beverage and providing beverage having uniform quality. In addition, the fermentation container 12 and the ingredient containers C1, C2 and C3 may be easily detached and installed, thereby improving cleanliness outside/inside the apparatus.

The fluid supply module 5 may include a tank 51, a pump 52 that pumps a fluid, such as water within the tank 51, and a heater 53 that heats the fluid pumped by the pump 52.

A thermal fuse 58 that interrupts a circuit to cutoff current applied to the heater 53 when a temperature is high may be installed in the heater 53.

The fluid supply module 5 may further include a safety valve 53 a. The safety valve 53 a may communicate with an inside of a heater case of the heater 53. The safety valve 53 a may restrict a maximum inner pressure of the heater case. For example, the safety valve 53 a may restrict the maximum inner pressure of the heater case to a pressure of about 3.0 bar.

The fluid supply module 5 may further include a temperature sensor 57 that measures a temperature of the fluid passing through the heater 53. The temperature sensor 57 may be installed in the heater 53. Alternatively, the temperature sensor 57 may be disposed at a portion of the supply channel 55 b behind the heater 53 in the flow direction of fluid. Also, the temperature sensor 57 may be installed in the first main channel 41.

When the pump 52 is driven, the fluid within the tank 51 may be introduced into the pump 52 through the tank discharge channel 55 a. The fluid discharged from the pump 52 may be heated in the heater 53 while flowing through the supply channel 55 b and then be guided to the first main channel 41.

When the beverage is dispensed, the beverage dispensing valve 64 may be opened. When the beverage is not dispensed, the beverage dispensing valve 64 may be maintained in a closed state.

The gas discharger 7 may be connected to the fermentation module 1 to discharge gas generated in the fermentation container 12. The gas discharger 7 may include a gas discharge channel 71 connected to the fermentation module 1, a gas pressure sensor 72 installed in the gas discharge channel 71, and a gas discharge valve 73 connected upstream of the gas pressure sensor 72 in the gas discharge channel 71 in a gas discharge direction.

The gas discharge channel 71 may be connected to the fermentation module 1, more particularly, the fermentation lid 107. A gas discharge channel connecting portion 121 to which the gas discharge channel 71 may be connected may be provided in the fermentation lid 107.

Gas within the fermentation container 12 may flow into the gas discharge channel 71 and the gas pressure sensor 72 through the gas discharge channel connecting portion 121. The gas pressure sensor 72 may detect a pressure of the gas discharged to the gas discharge channel 71 through the gas discharge channel connecting portion 121 within the fermentation container 12.

The gas discharge valve 73 may be opened when air is injected into the fermentation container 12 by the air injector 8. The fermentation and aging apparatus may uniformly mix the malt with the fluid by injecting air into the fermentation container 12. Foam generated in the liquid malt may be discharged from an upper portion of the fermentation container 12 to the outside through the gas discharge channel 71 and the gas discharge valve 73. The gas discharge valve 73 may be opened during the fermentation operation and then closed.

The gas discharger 7 may further include a safety valve 75 connected to the gas discharge channel 71. The safety valve 75 may be connected upstream of the gas pressure sensor 72 in the gas discharge channel 71 in the gas discharge direction. The safety valve 75 may restrict a maximum pressure of the fermentation container 12 and the gas discharge channel 71. For example, the safety valve 75 may restrict the maximum pressure of the fermentation container 12 and the gas discharge channel 71 to a pressure of about 3.0 bar.

The gas discharger 7 may further include a pressure release valve 76. The pressure release valve 76 may be connected to the gas discharge channel 71. The pressure release valve 76 and the gas discharge valve 73 may be selectively opened/closed. The gas discharge channel 71 may be branched to be respectively connected to the gas discharge valve 73 and the pressure release valve 76.

A noise reducing device 77 may be mounted on the pressure release valve 76. The noise reducing device 77 may include at least one of an orifice structure or a muffler structure, for example.

Even though the pressure release valve 76 is opened, an inner pressure of the fermentation container 12 may gradually decrease due to the noise reducing device 77. When fermentation of the beverage progresses, the pressure release valve 76 may be opened to release the pressure in a state in which the inner pressure of the fermentation container 12 increases. The noise reducing device 77 may effectively reduce noise generated due to a difference in pressure between the inside and outside of the fermentation container 12. The pressure release valve 76 may be open/close-controlled in a fermentation operation with relatively high internal pressure. That is, the fermentation and aging apparatus may effectively discharge unnecessary gas generated in the fermentation operation through the gas discharger 7.

The air injector 8 may be connected to the supply channel 55 b or the first main channel 41 to inject air. Hereinafter, for convenience of description, a case in which the air injector 8 is connected to the supply channel 55 b will be described as an example.

The air injector 8 may be connected to an opposite side of sub channel 91, which will be described hereinafter, with respect to the heater 53. The air injected by the air injector 8 may pass through the heater 53 to flow to the sub channel 91 together with residual fluid within the heater 53. Thus, residual fluid within the heater 53 may be removed to maintain a clean state of the heater 53.

Alternatively, air injected from the air injector 8 to the first main channel 41 may successively pass through the bypass channel 43 and the second main channel 42 and then be injected into the fermentation container 12. Thus, stirring or aeration may be performed in the fermentation container 12.

Alternatively, air injected from the air injector 8 to the first main channel 41 may be guided to the ingredient supplier 3 to flow to the ingredient container mounts 31, 32, and 33. Residual fluid or residue within the ingredient containers C1, C2, and C3 or the ingredient container mounts 31, 32, and 33 may flow to the second main channel 42 due to air injected by the air injector 8. The ingredient containers C1, C2, and C3 and the ingredient container mounts 31, 32, and 33 may be cleanly maintained by the air injected by the air injector 8.

The air injector 8 may include an air injection channel 81 connected to the supply channel 55 b or the first main channel 41 and an air pump 82 connected to the air injection channel 81. The air pump 82 may pump air to the air injection channel 81. An air injection check valve 83 that prevents fluid flowing to the supply channel 55 b by the pump 52 from being introduced into the air pump 82 through the air injection channel 81 may be installed in the air injection channel 81.

The air injector 8 may further include an air filter 82 a. The air filter 82 a may be provided in a suction portion of the air pump 82, and thus, external air may be suctioned into the air pump 82 by passing through the air filter 82 a. Thus, the air pump 82 may inject clean air into the air injection channel 81. That is, as the fermentation and aging apparatus includes the air injector 8, it is possible to smoothly supply air necessary for growing microorganisms during the fermentation operation of the beverage.

The air controller 15 may control a pressure between the inner wall of the fermentation tank 112 and the outer surface of the fermentation container 12. The air controller 15 may supply air into a space between the fermentation container 12 and the fermentation tank 112. On the other hand, the air controller 15 may exhaust the air within the space between the fermentation container 12 and the fermentation tank 112 to the outside.

The air controller 15 may include an air supply channel 154 connected to the fermentation module 1, and an exhaust channel 157 connected to the air supply channel 154 to exhaust the air to the outside. The air supply channel 154 may have a first end connected to the first main channel 41 and a second end connected to the fermentation module 1.

The air supply channel 154 may be connected to the fermentation module 1, more particularly, the fermentation lid 107. An air supply channel connecting portion 117 to which the air supply channel 154 may be connected may be provided in the fermentation module 1. The air supply channel connecting portion 117 may communicate with the space between the inner wall of the fermentation tank 112 and the outer surface of the fermentation container 12.

The air injected from the air injector 8 to the first main channel 41 may be guided between the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112 through the air supply channel 154. The air injector 8 may function as an air supplier that supplies air into the space between the fermentation container 12 and the fermentation tank 112 together with the air supply channel 154.

As described above, the air supplied into the fermentation tank 112 may press the fermentation container 12 between the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112. The beverage within the fermentation container 12 may be pressed by the fermentation container 12 pressed by the air. When the main valve 40 and the beverage dispensing valve 64 are opened, the beverage may pass through the main channel connecting portion 115 to flow to the second main channel 42. The beverage flowing from the fermentation container 12 to the second main channel 42 may be dispensed to the outside through the beverage dispenser 6.

The air pump 82 may supply air so that a predetermined pressure occurs between the fermentation container 12 and the fermentation tank 112. Thus, a pressure at which the beverage within the fermentation container 12 is easily dispensed may occur between the fermentation container 12 and the fermentation tank 112.

The air pump 82 may be maintained in an off state while the beverage is dispensed. When the beverage is completely dispensed, the air pump 82 may be driven for a next beverage dispensing and then stopped.

Thus, when the beverage is finished, the fermentation and aging apparatus may dispense the beverage within the fermentation container 12 to the beverage dispenser 6 in a state in which the fermentation container 1 is disposed within the fermentation module 1 without withdrawing the fermentation container 12 to the outside of the fermentation module 1.

The air controller 15 may include a separate air supply pump with respect to the air injector 8. In this case, the air supply channel 154 may be connected to the air supply pump, but may not be connected to the first main channel 41. However, injection of air into the fermentation container 12 by the air pump 82 and the supplying of air into the space between the fermentation container 12 and the fermentation tank 112 may be combined with each other to realize a compact product and reduce manufacturing costs.

The exhaust channel 157 may function as an air exhaust passage, through which the air between the fermentation container 12 and the fermentation tank 112 may be exhausted to the outside, together with a portion of the air supply channel 154. The exhaust channel 157 may be disposed outside of the fermentation module 1. The exhaust channel 157 may be connected to a portion of the air supply channel 154, which is disposed outside of the fermentation tank 112.

The air supply channel 154 may include a first channel connected between a connecting portion 157 a connected to the first main channel 41 and the exhaust channel 157 and a second channel connected between the connecting portion 154 a connected to the exhaust channel 157 and the air supply channel connecting portion 117. The first channel may be an air supply channel that guides the air pumped by the air pump 82 to the second channel. Also, the second channel may be an air supply and exhaust-combined channel that supplies the air passing through the air supply channel into the space between the fermentation tank 112 and the fermentation container 12 or guides the air discharged from the space between the fermentation tank 112 and the fermentation container 12 the connecting channel 157.

The exhaust channel 157 may be connected to an exhaust valve 156 that opens and closes the exhaust channel 157. The exhaust valve 156 may be opened so that the air between the fermentation container 12 and the fermentation tank 112 may be exhausted to the outside when the fermentation container 12 is expanded while the beverage is made. The exhaust valve 156 may be opened when the fluid is supplied by the fluid supply module 5. The exhaust valve 156 may be opened when the air is injected by the air injector 8.

The exhaust valve 156 may be opened so that the air between the fermentation container 12 and the fermentation tank 112 may be exhausted when the beverage within the fermentation container 12 is completely dispensed. The user may take the fermentation container 12 out of the fermentation tank 112 when the beverage is completely dispensed. This is done because safety accidents occur when the inside of the fermentation tank 112 is maintained at a high pressure. The exhaust valve 156 may be opened when the beverage within the fermentation container 12 is completely dispensed.

The air controller 15 may further include an air supply valve 159 that restricts the air pumped by the air pump 82 and supplied between the fermentation container 12 and the fermentation tank 112. The air supply valve 159 may be installed in the air supply channel 154. That is, the air supply valve 159 may be installed between the connecting portion 154 a of the first main channel 41 and the connecting portion 157 a of the exhaust channel 157 in the air supply channel 154.

The sub channel 91 may connect the fluid supply module 5 to the beverage dispenser 6. That is, the sub channel 91 may have a first end 91 a connected to the supply channel 55 b and a second end 91 b connected to the beverage dispensing channel 61.

The sub channel 91 may be connected between the pump 52 and the heater 53 with respect to the supply channel 55 b. Also, the sub channel 91 may be connected to the connecting portion 61 a of the second main channel 42 and the beverage dispensing valve 64 with respect to the beverage dispensing channel 61.

The fluid supplied by the pump 52 and the air pumped by the air pump 82 may be guided to the beverage dispensing channel 61 through the sub channel 91 and then may be dispensed to the dispenser 62. Thus, residual fluid or beverage remaining in the beverage dispenser 6 may be removed.

A sub valve 92 that opens and closes the sub channel 91 may be installed in the sub channel 91. The sub valve 92 may be opened to open the sub channel 91 when the beverage is dispensed, or cleaning is performed.

A sub check valve 93 that prevents the beverage in the beverage dispensing channel 61 from flowing back to the fluid supply module 5 may be installed in the sub channel 91. The sub check valve 93 may be disposed between the sub valve 92 and the beverage dispensing channel 61 with respect to the sub channel 91.

The sub channel 91 may function as a residual fluid removing channel of the fluid supply module 5. For example, when the air pump 82 is turned on in a state in which the air supply valve 159, the bypass valve 35, and the ingredient supply valve 310 are closed, the sub valve 92 is opened, and the air injected into the air injection channel 81 may pass through the heater 53 to flow to the sub channel 91. Then, the air may pass through the sub valve 92 to flow to the beverage dispensing channel 61 and then be dispensed to the dispenser 62. In this operation, the air may be dispensed together with fluid from the fluid supply module 5, more particularly, the residual fluid remaining in the heater 53 and the supply channel 55 b so that residual fluid may be removed.

In addition, the sub channel 91 may function as a cleaning channel. That is, a beverage may be partially dispensed by the dispenser 62, and when a long period of time has elapsed before a next beverage dispensing, fluid may flow to the sub channel 91 to clean the dispenser 62 before the next beverage dispensing is performed.

FIG. 2 is a flowchart of a method for controlling a fermentation and aging apparatus according to an embodiment. The fermentation and aging apparatus according to this embodiment may include cleaning operations (S100 and S200) for cleaning the channels. The cleaning operations (S100 and S200) may be separately performed with respect to a beverage making operation. The cleaning operations (S100 and S200) may be performed before and after the beverage making operation.

Also, the cleaning operations (S100 and S200) may be performed by a user input during the beverage making operation. In this case, like a primary fermentation operation (S160) or a secondary fermentation operation (S170), which will be described hereinafter, the cleaning operations (S100 and S200) may be performed while the channel connected to the fermentation module 1 is closed, and the ingredients are not contained in the ingredient suppler 3.

The cleaning operations (S100 and S200) may be performed in a state in which the ingredient containers are accommodated in the ingredient supplier 3, and the fermentation container 12 is accommodated in the fermentation module 1. The user may input a cleaning command through an input interface 420 (referring to FIG. 3 ), a remote controller, or a portable terminal. A controller 460 may control the fermentation and aging apparatus to perform the cleaning operations (S100 and S200) according to the input of the cleaning command.

Also, the user may input a beverage making command through the input interface 420, a remote controller, or a portable terminal. The controller 460 may control the fermentation and aging apparatus to perform the cleaning operations (S100 and S200) before and after the beverage making operation according to the input of the beverage making operation.

The controller 460 may supply a fluid, such as water of the tank 51 to the inner channels and the ingredient supplier 3 in the cleaning operation. The supplied fluid may be discharged to the outside through the dispenser 62 together with foreign matter or residue present in the channels and the ingredient supplier 3.

In the fermentation and aging apparatus, the cleaning operation may be performed during a predetermined cleaning time. After the predetermined cleaning time, the cleaning operation may be completed. As the cleaning operation is provided, it is possible to prevent internal contamination or microorganism propagation of the fermentation and aging apparatus.

The beverage making operation of making a beverage may be performed in the fermentation and aging apparatus according to this embodiment. The user may seat the fermentation container 12 on or in the fermentation module 1 for the beverage making operation. In this case, some (for example, malt) of ingredients may be received in the fermentation container 12. The malt may be received in the form of malt oil.

The user may insert the plurality of ingredient containers C1, C2, and C3 into the ingredient supplier 3 before or after the fermentation container 12 is seated. The user may input the beverage making command through the input interface 420, the remote controller, or the mobile terminal. The controller 460 may control the fermentation and aging apparatus to perform the beverage making operation according to the input of the beverage making command.

The beverage making operation may include a fluid supply operation (S110). The fluid supply operation (S110) may be a liquid malt formation operation of mixing the malt in the fermentation container 12 with heated fluid to form liquid malt.

The controller 460 may turn on the pump 52 to introduce the fluid from the tank 51 into the fermentation container 12, in the fluid supply operation (S110). According to an embodiment, to introduce heated fluid into the fermentation container 12, the fluid supply module 5 may further include the heater 53. The fluid discharged from the tank 51 may pass through the pump 52, may flow to the heater 53, and may be heated by the heater 53. Fluid heated by the heater 53 may be introduced into the fermentation container 12 through a channel between the fluid supply module 5 and the fermentation module 1. The heated fluid introduced into the fermentation container 12 may be mixed with the malt contained in the fermentation container 12, and the malt in the fermentation container 12 may be mixed with the fluid and gradually diluted. As the heated fluid is supplied to the fermentation container 12, the malt accommodated in the fermentation container 12 may be quickly uniformly mixed with the heated fluid.

The controller 460 may perform the fluid supply operation (S110) until an amount of accumulated fluid detected by the flow meter 56 reaches a target flow rate, and when the amount of accumulated fluid detected by the flow meter 56 reaches the target flow rate, the fluid supply operation (S110) may be ended. When the fluid supply operation (S110) is complete, the controller 460 may turn off the pump 52 and the heater 53.

The beverage making operation may include a fermentation tank cooling operation (S120). When the fluid supply operation (S110) is complete, the fermentation tank cooling operation (S120) for cooling the fermentation tank 112 or the fermentation container 12 may be performed.

The controller 460 may control the temperature controller 11 to cool the fermentation container 12. The controller 460 may control the refrigerant cycle device 3 to cool the fermentation container 12. When the refrigerant cycle device 3 is driven, the fermentation container 12 may be gradually cooled, and also, the liquid malt accommodated in the fermentation container 12 may be cooled. The controller 460 may control the refrigerant cycle device 13 according to the temperature detected by the temperature sensor 16 installed in the fermentation module 1.

The beverage making operation may include an additive introducing operation (S130). The fermentation and aging apparatus may perform the additive introducing operation (S130) while performing the cooling operation (S120). For example, the fermentation and aging apparatus may perform the additive introducing operation (S130), when the temperature sensed by the temperature sensor 16 reaches a specific temperature value higher than the cooling temperature set for the cooling operation (S120).

In the additive introducing operation (S130), ingredients received in the ingredient supplier 3 may be introduced into the fermentation container 12. The controller 460 may turn on the pump 52. When the pump 52 is turned on, the fluid in the tank 51 may be introduced into the ingredient supplier 3 by passing through the pump 52 and a channel between the fluid supply module 5 and the ingredient supplier 3. Fluid introduced into the ingredient supplier 3 may be mixed with the ingredient contained in the ingredient supplier 3 and introduced into the fermentation container 12 together with the ingredient.

The controller 460 may complete the additive introducing operation (S130) when the accumulated flow rate detected by the flow meter 56 reaches the additive introduction target flow rate from a start of the additive introducing operation (S130). When the additive introducing operation (S130) is completed, the controller 460 may turn off the pump 52.

The beverage making operation may include an ingredient supplier residual fluid removing operation (S140). When the additive introducing operation (S130) is complete, the ingredient supplier residual fluid removing operation (S140) of removing residual fluid from the ingredient supplier 3 may be performed.

In the ingredient supplier residual fluid removing operation (S140), the controller 460 may turn on the air pump 82. When the air pump 82 is turned on, air may be introduced into the ingredient supplier 3 through a channel between the air pump 82 and the ingredient supplier 3. The air introduced into the ingredient supplier 3 may push residual fluid in the ingredient supplier 3 into a channel between the ingredient supplier 3 and the fermentation module 1. The air flowing into the channel may be introduced into the fermentation container 12 together with the residual fluid. Accordingly, ingredients and fluid, which are not extracted, but remain in the ingredient supplier 3, may be entirely introduced into the fermentation container 12.

The controller 460 may turn on the air pump 82 for a predetermined residual fluid removal time and may end the ingredient supplier residual fluid removing operation (S140) after the predetermined residual fluid removal time has elapsed. When the ingredient supplier residual fluid removing operation (S140) is complete, the controller 460 may turn on the air pump 82.

The beverage making operation may further include an air supplying operation (S150). The fermentation and aging apparatus may complete the cooling operation (S120) when the temperature sensed by the temperature sensor 16 is equal to or less than a cooling temperature at least one time after the cooling operation (S120) is commenced and the refrigerant cycle device is turned on. The fermentation and aging apparatus may perform the air supplying operation (S150) of supplying air into the fermentation container 12 to mix liquid malt, after the cooling operation (S120) is completed.

In the air supplying operation (S150), the controller 460 may turn on the air pump 82. While the air pump 82 is in an ON state, the air may be introduced into the fermentation container 12 by passing through the channel between the air pump 82 and the fermentation module 1. The air introduced into the fermentation container 12 as described above may collide with the liquid malt to help the malt be more uniformly mixed with the heated fluid. In addition, the air colliding with the liquid malt may supply oxygen to the liquid malt. In other words, stirring and aeration may be performed.

The controller 460 may turn on the air pump 82 and may mix the air with the liquid malt for a predetermined mixing time, and may complete the air supplying operation (S150) when the predetermined mixing time has elapsed after the air pump 82 is turned on. In the air supplying operation (S150), the controller 460 may turn off the air pump 82.

The beverage making operation may include the fermentation operation (S160 and S170). The fermentation operation may include the primary fermentation operation (S160) and the secondary fermentation operation (S170).

The controller 460 may control the temperature controller 11 such that the temperature measured by the temperature sensor 16 is maintained at a primary fermentation target temperature in the primary fermentation operation. The controller 460 may periodically open or close the gas discharge valve 73 that opens or closes a channel between the fermentation container 12 and the outside, and may store the pressure sensed by the gas pressure sensor 72 in a memory 450 while the gas discharge valve 73 is closed. The controller 460 may complete the primary fermentation operation (S160), when a variation in pressure periodically sensed by the gas pressure sensor exceeds a primary fermentation reference pressure variation.

The controller 460 may commence the secondary fermentation operation (S170) after the primary fermentation operation (S160) is completed. The controller 460 may control the temperature controller 11 such that the temperature measured by the temperature sensor 16 becomes a secondary fermentation target temperature in the secondary fermentation operation (S170). The secondary fermentation target temperature may be equal to the first fermentation target temperature; however, embodiments are not limited thereto.

The controller 460 may open and close the gas discharge valve 73 based on the inner pressure of the fermentation tank 112 after the secondary fermentation operation (S170) is commenced. When the variation in the pressure sensed by the gas pressure sensor 72 exceeds a secondary fermentation pressure variation, or when the secondary fermentation progress time exceeds the predetermined secondary fermentation time, the controller 460 may determine that the secondary fermentation is completed and may end the secondary fermentation operation (S170).

Alternatively, the controller 460 may open and close the gas discharge valve 73 such that the inner pressure of the fermentation tank 112 is maintained to be within a secondary fermentation pressure range for the predetermined secondary fermentation time. The controller 460 may complete the secondary fermentation operation (S170) when the predetermined secondary fermentation time has elapsed. That is, the fermentation and aging apparatus may naturally produce carbonic acid in the beverage through the secondary fermentation operation.

The beverage making operation may include an aging operation (S180). When the primary fermentation operation (S160) and the secondary fermentation operation (S170) are completed, the aging operation (S180) may be performed.

The controller 460 may stand by for an aging time in the aging operation (S180), and may control the temperature controller 11 such that the temperature of the beverage is maintained between an upper limit and a lower limit of a target aging temperature for the aging time.

When the aging time has elapsed, the beverage is completely made. However, if necessary, the aging operation (S180) may be omitted and the beverage making may be completed when the secondary fermentation operation (S170) is completed.

The controller 460 may display that the beverage making is completed, through a display 430 (see FIG. 3 ). In addition, the controller 460 may inform the user of information on the beverage making operation through a communication interface 410 or the display 430. Therefore, the user may conveniently check the beverage making operation and easily make the beverage through the fermentation and aging apparatus by themselves.

The controller 460 may maintain the temperature of the fermentation container 12 between an upper limit and a lower limit of a target drinking temperature until a beverage dispensing operation (S190) to be described hereinafter is completed.

According to an embodiment, the fermentation and aging apparatus may further perform the beverage dispensing operation (S190) of dispensing a beverage after the beverage is completely made. In the beverage dispensing operation (S190), the user may dispense a beverage by operating the dispenser 62. When the user opens the dispenser 62, the beverage in the fermentation container 12 may be dispensed through the dispenser 62 after passing through the channel between the fermentation module 1 and the dispenser 62.

The user may dispense the beverage at least once through the dispenser 62. In other words, the beverage dispensing operation may be performed at least once, and the controller 460 may determine whether the beverage dispensing is completed by using information, such as a time during which the dispenser 62 is opened.

When the controller 460 determines that all of the beverage in the fermentation container 12 is dispensed, and thus, the beverage dispensing operation is completed, the controller 460 may further perform a cleaning operation (S200) after the beverage making operation and the beverage dispensing operation. The cleaning operation (S200) may be similar to the cleaning operation (S100) before the beverage making operation.

As described above, when the beverage is made in the fermentation and aging apparatus, the fermentation container 12, in which an object to be fermented is accommodated, may be put into the fermentation tank 112. However, the fermentation tank 112 or the fermentation module 1 may not be provided with a separate sensor to detect whether the fermentation container 12 has been put into the fermentation tank 112, due to pressure change, or temperature change, for example, occurring while the beverage is made.

When the beverage making process is performed in a state in which the fermentation container 12 is not put into the fermentation tank 112, the beverage may not be normally made. In addition, as a fluid, such as water or additives are directly introduced into the fermentation tank 112, the inside of the fermentation tank 112 may be contaminated.

The fermentation and aging apparatus according to an embodiment may detect whether the fermentation container 12 is put into the fermentation tank 112 even if a separate sensor to detect whether the fermentation container 12 is put into the fermentation tank 112 is not provided. Embodiments related thereto will be described with reference to FIGS. 3 to 9 .

FIG. 3 is a schematic block diagram illustrating components for controlling a fermentation and aging apparatus according to an embodiment. The components for controlling the fermentation and aging apparatus, which are illustrated in FIG. 3 , are not essential components to realize the fermentation and aging apparatus. Accordingly, the fermentation and aging apparatus according to embodiments may include more or less components.

Referring to FIG. 3 , the fermentation and aging apparatus may include communication interface 410 to communicate with a terminal, such as a smart phone or a tablet PC, for example, or a server, for example. For example, the controller 460 may receive a request for performing a function of making a beverage from a terminal of the user or recipe information through the communication interface 410. In addition, the controller 460 may transmit various pieces of information, such as an operation of the fermentation and aging apparatus, a beverage making state, and a storage state of the beverage, for example, to the terminal or the server through the communication interface 410.

The communication interface 410 may include a module to support at least one of various wireless/wired communication schemes, which are well known. For example, the communication interface 410 may include a short-range wireless communication module, such as Bluetooth or Near Field Communication (NFC), or a wireless Internet module, such as a wireless local area network (WLAN) module. For example, the NFC module may obtain recipe information corresponding to a beverage preparation pack or a beverage preparation kit from a NFC tag as the NFC tag included in the beverage preparation pack or the beverage preparation kit approaches within a predetermined distance.

The input interface 420 may be configured to receive various requests or commands from a user. For example, the input interface 420 may include a rotary knob 422, a touch pad 424 (or a touch screen), other buttons, and/or a microphone, for example. The controller 460 may receive a request for execution of a beverage making function, recipe information, and control commands for various operations of the fermentation and aging apparatuses through the input interface 420, for example.

According to an embodiment, the fermentation and aging apparatus may further include a code recognizer to obtain recipe information. For example, the code recognizer may be implemented with a quick response (QR) code recognizer to recognize a QR code included in a beverage preparation pack or a beverage preparation kit, and obtain recipe information corresponding to the recognized QR code.

The display 430 may output various pieces of information associated with an operation or state of the fermentation and aging apparatus and various pieces of information associated with the beverage which is being made or stored in the fermentation and aging apparatus. The display 430 may be implemented with a liquid crystal display (LCD), a light emitting diode (LED), and/or an organic light emitting diode (OLED) display, for example.

For example, the display 430 may output the information in a graphic form or a text form. The fermentation and aging apparatus may further include a speaker to output the information in the form of a voice. The controller 460 may output the information through various combinations of a graphic, a text, and/or voice using the display 430 and the speaker.

The memory 450 may store various pieces of information or data associated with the operation of the fermentation and aging apparatus. For example, the memory 450 may store recipe information for beverages that may be made or various program data for the operation of the fermentation and aging apparatus. In addition, the memory 450 may store various graphic data associated with screens displayed through the display 430.

In addition, the memory 450 may store values for making beverages corresponding to multiple pieces of recipe information. For example, the values for making the beverages may include a cooling temperature described with reference to FIG. 2 , a primary fermentation target temperature, a primary fermentation reference pressure variation, a secondary fermentation target temperature, a secondary fermentation pressure range, or a secondary fermentation time. In addition, the values for making the beverages may further include a first open time, a close time, and a second open time, for example, which will be described hereinafter.

The memory 450 may further store reference data (reference time and reference pressure) for detecting whether the fermentation container 12 is put into the fermentation tank 112. In addition, the memory 450 may further include control data when detecting that the fermentation container 12 is put into the fermentation tank 112 and control data when detecting that the fermentation container 12 is not put into the fermentation tank 112.

The controller 460 may control an overall operation of the fermentation and aging apparatus. In this case, the controller 460 may refer to at least one controller. The at least one controller may be implemented in hardware, such as a CPU, an application processor, a microcomputer, an integrated circuit, and/or an application specific integrated circuit (ASIC), for example.

The controller 460 according to an embodiment may control the air pump 82 to inject air into the fermentation tank 112 in a state of closing the gas discharge valve 73 and the exhaust valve 156 to seal the fermentation tank 112, when the beverage start to be made according to a beverage making start request. The controller 460 may accurately detect whether the fermentation container 12 is put into the fermentation tank 112, based on the pressure measured through the gas pressure sensor 72 during air injection.

Embodiments related to operation of the controller 460 will be described with reference to FIGS. 4 to 9 . FIG. 4 is a flowchart of a control operation of a fermentation and aging apparatus according to an embodiment.

Referring to FIG. 4 , the fermentation and aging apparatus may receive a beverage making start request through the input interface 420 (S400). In response to the beverage making start request, the fermentation and aging apparatus may close the gas discharge valve 73 and the exhaust valve 156 (S410). The controller 460 may seal the fermentation tank 112, by closing the gas discharge valve 73 and the exhaust valve 156 in response to the received the beverage making start request.

As described above with reference to FIG. 1 , when the fermentation container 12 is normally put into the fermentation tank 112, the gas discharge channel 71 opened and closed by the gas discharge valve 73 may be connected with the internal space of the fermentation container 12. In addition, the exhaust channel 157 opened and closed by the exhaust valve 156 may be connected with a space between the fermentation container 12 and the fermentation tank 112.

In contrast, when the fermentation container 12 is not put into the fermentation tank 112, each of the gas discharge channel 71 and the exhaust channel 157 may be connected with the internal space of the fermentation tank 112. In some embodiments, the gas discharge channel 71 may be implemented not to be connected with the internal space of the fermentation tank 112.

When the cleaning operation (S100) before the beverage making operation described above with reference to FIG. 2 is performed according to the beverage making start request, operation S410 may be performed after the cleaning operation (S100) before the beverage making operation.

The fermentation and aging apparatus may drive the air pump 82 after sealing the fermentation tank 112 (S420). The controller 460 may drive the air pump 82 to inject air into the fermentation tank 112 or the fermentation container 12. The controller 460 may open the bypass valve 35 and the main valve 40 to inject air through the main channel 42 and close the air supply valve 159 not to inject air through the air supply channel 154.

In some embodiments, the fermentation and aging apparatus may include a first air pump connected with the main channel 42 and a second air pump connected with the air supply channel 154. In this case, the controller 460 may drive the first air pump and may not drive the second air pump.

When the fermentation container 12 is normally put into the fermentation tank 112, air supplied by driving the air pump 82 may be injected into the fermentation container 12. In contrast, when the fermentation container 12 is not put into the fermentation tank 112, the air may be injected into the fermentation tank 112.

The fermentation and aging apparatus may measure a pressure using the gas pressure sensor 72 while the air pump 82 is driven (S430). The controller 460 may periodically or continuously measure the pressure through the gas pressure sensor 72 simultaneously with driving of the air pump 82 or after driving of the air pump 82.

The fermentation and aging apparatus may determine whether the measured pressure reaches a reference pressure within a reference time (S440). The reference time and the reference pressure may be preset or predetermined when a manufacturer releases a product through simulation or tests.

When the measured pressure reaches the reference pressure within the reference time (YES of S440), the fermentation and aging apparatus may detect that the fermentation container 12 is normally put into the fermentation tank 112 (S450). In this case, the fermentation and aging apparatus may stop driving of the air pump 82, open the gas discharge valve 73 and the exhaust valve 156 (S455), and start a hot fluid supply operation according to the beverage making process (S460).

When the fermentation container 12 is normally put into the fermentation tank 112, a volume of the fermentation container 12 may increase according to air injection. As a space between the fermentation container 12 and the fermentation tank 112 is sealed, increasing speed of the volume of the fermentation container 12 may gradually decrease and the internal pressure of the fermentation container 12 may gradually increase.

When the fermentation container 12 is normally put into the fermentation tank 112, the pressure measured by the gas pressure sensor 72 may reach the reference pressure within the reference time from a driving time of the air pump 82. The controller 460 may detect that the fermentation container 12 is normally put into the fermentation tank 112, when the measured pressure reaches the reference pressure within the reference time.

According to the result of detection, the controller 460 may stop driving of the air pump 82 and open the gas discharge valve 73 and the exhaust valve 156. As the gas discharge valve 73 and the exhaust valve 156 are opened, the pressure of the fermentation tank 112 and the fermentation container 12 may be returned to the pressure before driving of the air pump 82. Thereafter, the controller 460 may perform the beverage making process, such as the hot fluid supply operation.

In contrast, when the measured pressure does not reach the reference pressure within the reference time (NO of S440), the fermentation and aging apparatus may detect that the fermentation container 12 is not put into the fermentation tank 112 (S470). In this case, the fermentation and aging apparatus may stop driving of the air pump 82, open the gas discharge valve 73 and the exhaust valve 156 (S475), and output a request for putting the fermentation container 12 into the fermentation tank 112 (S480).

When the fermentation container 12 is not put into the fermentation tank 112, air may be injected into the fermentation tank 112 when the air pump 82 is driven. In this case, although the internal pressure of the fermentation tank 112 may increase, as the internal space of the fermentation tank 112 is larger than that of the fermentation container 12, the increasing speed of the pressure of the fermentation tank 112 may be lower than the increasing speed of the pressure of the fermentation container 12 when the fermentation container 12 is put into the fermentation tank 112.

Therefore, the pressure measured by the gas pressure sensor 72 may not reach the reference pressure within the reference time. The controller 460 may detect that the fermentation container 12 is not put into the fermentation tank 112, when the measured pressure does not reach the reference pressure within the reference time.

In some embodiments, when the gas discharge channel 71 is implemented not to be connected with the internal space of the fermentation tank 112, the pressure measured by the gas pressure sensor 72 may not be changed. Similarly, the pressure measured by the gas pressure sensor 72 may not reach the reference pressure within the reference time. Accordingly, the controller 460 may detect that the fermentation container 12 is not put into the fermentation tank 112.

According to the result of detection, the controller 460 may stop driving of the air pump 82 and open the gas discharge valve 73 and the exhaust valve 156, thereby discharging the air injected into the fermentation tank 112. In addition, the controller 460 may stop the beverage making process and output a request for putting the fermentation container 12 into the fermentation tank 112 through an output interface, such as the display 430. Alternatively, the controller 460 may transmit a signal corresponding to the request for putting the fermentation container 12 into the fermentation tank 112 to a user terminal through the communication interface 410.

Thereafter, through the input interface 420, the controller 460 may receive the input indicating that the fermentation container 12 is put into the fermentation tank 112 or the beverage making start request again and perform operations S410 to S480 again. That is, the fermentation and aging apparatus may determine whether the fermentation container is normally put into the fermentation tank 112 using the air pump 82 and the gas pressure sensor 72, before the beverage making process is performed according to the beverage making start request. Therefore, it is possible to prevent a problem in which the beverage is not normally made or the inside of the fermentation tank 112 is contaminated as fluid, such as water or additives are directly introduced into the fermentation tank 112.

FIGS. 5 to 6 are views showing examples in which a fermentation container is put into a fermentation tank in relation to the control operation of FIG. 4 . FIG. 7 is a view showing an example of a graph showing pressure change when the fermentation container is put into the fermentation tank.

Referring to FIG. 5 , when the fermentation container 12 is put into the fermentation tank 112, the gas discharge channel 71 may be connected with the internal space of the fermentation container 12 and the exhaust channel 157 may be connected with the space between the fermentation container 12 and the fermentation tank 112. As the gas pressure sensor 72 is disposed in the gas discharge channel 71, the pressure measured by the gas pressure sensor 72 may correspond to the internal pressure of the fermentation container 12.

When the beverage making start request is received, the controller 460 may close the gas discharge valve 73 and the exhaust valve 156 to seal the inside of the fermentation tank 112 and the fermentation container 12. The controller 460 may drive the air pump 82 to inject air into the fermentation tank 112. The controller 460 may open the main valve 40 and the bypass valve 35 and close the air supply valve 159, thereby injecting air through the main channel 42.

In some embodiments, the fermentation and aging apparatus may include the first air pump connected with the main channel 42 and the second air pump connected with the air supply channel 154. In this case, the controller 460 may drive the first air pump and may not drive the second air pump.

Referring to FIGS. 5 and 6 , air which has passed through the main channel 42 may be injected into the internal space of the fermentation container 12. As air is injected into the internal space of the fermentation container 12, the internal pressure of the fermentation container 12 measured through the gas pressure sensor 72 may increase. As the internal pressure of the fermentation container 12 increases, the volume of the fermentation container 12 may increase (expand). As the volume of the fermentation container 12 increases, the volume of the space between the fermentation tank 112 and the fermentation container 12 may decrease to correspond to the internal pressure of the fermentation container 12.

As shown in FIG. 7 , as air is injected into the internal space of the fermentation container 12, the pressure measured through the gas pressure sensor 72 may gradually increase. The increasing speed of the pressure may vary according to the temperature of the fermentation container 12. For example, the increasing speed of the pressure when the fermentation container 12 stored at a room temperature, for example, 20° C., is put into the fermentation tank 112 may be higher than the increasing speed of the pressure when the fermentation container 12 put in cold storage, for example, 5° C., is put into the fermentation tank 112.

That is, the reference time and the reference pressure may be set in consideration of the temperature of the fermentation container 12. For example, in the case where the reference time and the reference pressure are set to 70 seconds and 0.1 bar, the controller 460 may normally detect that the fermentation container 12 is input into the fermentation tank 112 when the fermentation container 12 is stored at the room temperature and is put in cold storage.

FIG. 8 is a view showing examples in which a fermentation container is not put into a fermentation tank in relation to the control operation of FIG. 4 . FIG. 9 is a view showing an example of a graph showing pressure change when the fermentation container is not put into the fermentation tank.

Referring to FIG. 8 , when the fermentation container 12 is not put into the fermentation tank 112, each of the gas discharge channel 71 and the exhaust channel 157 may be connected with the internal space of the fermentation tank 112. In some embodiments, the gas discharge channel 71 may be implemented not to be connected with the internal space of the fermentation tank 112.

When the gas discharge channel 71 is connected with the internal space of the fermentation tank 112, the pressure measured by the gas pressure sensor 72 may correspond to the internal pressure of the fermentation tank 112. In contrast, when the gas discharge channel 71 is not connected with the internal space of the fermentation tank 112, the pressure measured by the gas pressure sensor 72 may not be changed.

When the beverage making start request is received, the controller 460 may close the gas discharge valve 73 and the exhaust valve 156 to seal the inside of the fermentation tank 112. The controller 460 may drive the air pump 82 to inject air into the fermentation tank 112. The controller 460 may open the main valve 40 and the bypass valve 35 and close the air supply valve 159, thereby injecting air through the main channel 42.

In some embodiments, the fermentation and aging apparatus may include the first air pump connected with the main channel 42 and the second air pump connected with the air supply channel 154. In this case, the controller 460 may drive the first air pump and may not drive the second air pump.

Unlike to the embodiments of FIGS. 5 to 6 , as the fermentation container 12 is not put into the fermentation tank 112, air which has passed through the main channel 42 may be injected into the internal space of the fermentation tank 112. As air is injected into the internal space of the fermentation tank 112, the pressure measured through the gas pressure sensor 72 may increase. However, as air is injected into the fermentation tank 112 which is wider than the fermentation container 12, the increasing speed of the pressure may be slower than the increasing speed of the pressure when the fermentation container 12 is put into the fermentation tank 112.

That is, as shown in FIG. 9 , when the fermentation container 12 is not put into the fermentation tank 112, the pressure measured through the gas pressure sensor 72 may not reach the reference pressure within the reference time. When the measured pressure does not reach the reference pressure within the reference time, the controller 460 may detect that the fermentation container 12 is not put into the fermentation tank 112.

In some embodiments, even if the gas discharge channel 71 is implemented not to be connected with the internal space of the fermentation tank 112, the pressure measured by the gas pressure sensor 72 may not reach the reference pressure within the reference time. Although only the embodiment in which the controller 460 closes the exhaust valve 156 to close the exhaust channel 157 is shown in FIGS. 4 to 9 , the exhaust valve 156 may be in an open state in some embodiments. In this case, when the air pump 82 is driven in a state in which the fermentation container 12 is accommodated in the fermentation tank 112, the fermentation container 12 may expand to correspond to the inner wall of the fermentation tank 112. Thereafter, as air is continuously injected, the internal pressure of the fermentation container 12 may increase.

In contrast, when the air pump 82 is driven in a state in which the fermentation container 12 is not accommodated in the fermentation tank 112, air injected into the fermentation tank 112 may be discharged to the outside through the exhaust channel 157. Therefore, the internal pressure of the fermentation tank 112 may not increase to a predetermined pressure or more. That is, even if the exhaust valve 156 is in an open state, the controller 460 may detect whether the fermentation container 12 is put into the fermentation tank 112 based on the pressure measured using the gas pressure sensor 72.

According to embodiments disclosed herein, the fermentation and aging apparatus may determine whether the fermentation container is normally put into the fermentation tank using the air pump and the gas pressure sensor, before the beverage making process is performed according to the beverage making start request. Therefore, it is possible to prevent a problem in which the beverage is not normally made or the inside of the fermentation tank is contaminated as fluid, such as water or additives are directly introduced into the fermentation tank, by starting the beverage making process even when the fermentation container is not put into the fermentation tank.

In addition, the fermentation and aging apparatus may detect whether the fermentation container is put into the fermentation tank using the air pump and the gas pressure sensor provided to make the beverage, without a separate sensor to detect whether the fermentation container is put into the fermentation tank. Therefore, it is possible to prevent an increase in cost and process due to provision of a separate sensor.

Embodiments disclosed herein provide a fermentation and aging apparatus capable of determining whether a fermentation container is put into a fermentation tank even if a separate sensor is not provided in the fermentation tank in response to a beverage making start request.

The fermentation and aging apparatus according to embodiment disclosed herein may detect whether the fermentation container, in which an object to be fermented is accommodated, is normally put into the fermentation tank, before starting to make a beverage according to a beverage making start request. The fermentation and aging apparatus may close a first channel and a second channel connected with the fermentation tank, drive an air pump to supply air to the fermentation tank, and detect whether the fermentation container is put into the fermentation tank based on pressure detected through a pressure sensor disposed in the first channel.

When the fermentation container is put into the fermentation tank, the first channel may be connected with an internal space of the fermentation container, and the second channel may be connected with a space between the fermentation container and the fermentation tank. In addition, air supplied by the air pump may be injected into the internal space of the fermentation container.

When the fermentation container is not put into the fermentation tank, the second channel may be connected with an internal space of the fermentation tank, and air supplied by the air pump may be injected into the internal space of the fermentation tank. An increasing speed in pressure measured through the pressure sensor when the fermentation container is put into the fermentation tank may be higher than an increasing speed in pressure when the fermentation container is not put into the fermentation tank. The fermentation and aging apparatus may detect that the fermentation container is put into the fermentation tank, when the pressure measured through the pressure sensor reaches reference pressure within a reference time.

The fermentation and aging apparatus may perform a beverage making process when detecting that the fermentation container is put into the fermentation tank, and make a request for putting the fermentation container into the fermentation tank without performing the beverage making process when detecting that the fermentation container is not put into the fermentation tank.
